Embracing the 3-Month Rule: A Pragmatic Approach to Non-Scalable Solutions in Tech Development
In the world of tech startups, a common piece of wisdom from entrepreneur Paul Graham encourages innovators to “do things that don’t scale.” However, the challenge lies in the practical application of this advice, particularly in coding and infrastructure development. After dedicating eight months to my AI podcast platform, I’ve established a straightforward yet effective framework: any unscalable solution is granted a lifespan of three months. Beyond that period, we either elevate it to a robust solution or phase it out.
This philosophy starkly contrasts with how many engineers are trained. We often aim for scalable solutions, diving straight into design patterns, microservices, and sophisticated architectures designed for vast user bases. However, for startups, pursuing scalability too early can resemble expensive procrastination—investing effort into optimizing for hypothetical users with needs that may never materialize. My three-month approach compels me to create straightforward, sometimes imperfect code that ships quickly, allowing me to uncover the real needs of my users.
Infrastructure Hacks That Prove Smart Decisions
1. Unified Virtual Machine (VM) Deployment
I opted for a single $40/month VM to host my entire application, which includes the database, web server, background jobs, and Redis. While it may seem risky with zero redundancy and manual backups, this strategy has provided me with insights into my resource consumption far quicker than traditional capacity planning methods ever could. I discovered that my platform, which I initially presumed was “AI-heavy,” actually requires a modest peak of 4GB of RAM. Had I proceeded with a complex Kubernetes setup, I would have found myself managing idle containers rather than actively scaling.
Interestingly, when issues arise—which they’ve done twice so far—I gain valuable information about unexpected breaking points, reinforcing the reality of what my system truly demands.
2. Hardcoded Configurations for Agility
By utilizing hardcoded configurations throughout my codebase, such as:
python
PRICE_TIER_1 = 9.99
PRICE_TIER_2 = 19.99
MAX_USERS = 100
AI_MODEL = "gpt-4"
I eliminate the necessity for config files or environment variables. This approach allows me to quickly use search commands to track changes or updates. In three months, I’ve only modified these constants three times, resulting in a mere 15 minutes for redeployment compared to the 40

This post offers a compelling perspective on embracing non-scalable, rapid iteration approaches early on—a strategy often undervalued in the pursuit of scalability. The “3-month rule” is a pragmatic way to balance speed and product validation; it encourages teams to prioritize learning and agility over premature optimization.
Your infrastructure hacks, such as using a single VM and hardcoded configs, exemplify the “build fast, learn fast” philosophy—allowing for quick feedback loops that inform future scaling decisions. It’s a reminder that understanding real-world usage and system demands through simple setups can save both time and resources in the long run.
In my experience, this approach mitigates the paralysis that often accompanies trying to architect perfect, scalable systems from the outset. Instead, it fosters a mindset of continuous improvement—layering in complexity only when genuinely justified by user growth or stability requirements. Thanks for sharing this insightful framework; it’s a valuable contribution to the startup mindset!
